About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6233987310. Listed at 16 retailers as of October 28, 2026, with prices from €2,777 to €6,443, a €3,665 spread on the same certified stone. NZ Jewellers lists it at €6,443. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
